It's part of the
internet generation,
You think people weren't using the internet 25 years ago?
People were, but not that many. We'd only just started to install
ethernet, back then (at SLAC, this was).
What does Ethernet use at SLAC have to do with the number of people
using the Internet?
Only to the extent that not many people were networked, even at Labs.
You mean labs; but I sort of get your point.
Thing is, Ethernet is merely one of many networking protocols. `Just
starting to install Ethernet' doesn't mean that the place wasn't
networked before, y'see.
Well, in practice it does. Hmmm, OK, there was DECnet at SLAC before,
but only point to point links. Once Ethernet started getting laid
around, there was some chance that it would arrive more generally in
people's offices. Ethernet is only layer 0 (if I remember the stack
correctly). You still need software above that, we were using XNS in the
early to mid 80s. TCP/IP started to come in I'd say mid to late 80s.
Prior to and during the above, the average person in their office had a
9600bps connection to mainframes via a Switch (Gandalf at CERN and Micom
at SLAC). You could therefore get your VT100 compatible connected to an
IBM or VAX host, for local login purposes. If connected to a VAX, there
was some chance you could then use DECnet to remote login to some
distant host. During the 80s, most of SLAC's external networking was via
BITNET over a 9600bps connection (even this slow speed allowed a lot of
e-mail and file transfer to be done) and external DECnet connections
(can't remember how these were implemented).
